Troubleshooting
Measures
Check pump (temperature sensor). For measures
see failure Bearing Temp.
Check cable conections.
Check if the Pt 100 is connected to the corre-
sponding sensor cable. The sensor cables are
marked with COOLING WATER or BASFLANGE
(TMS-sensor).
Check cooling temperature sensor.
For Pin assignment see Fig. 44.
Measure the resistance between pins 1 and 3 of
the cooling temp. sensor.The resistance is typical-
ly between 110 and 150 Ohm (20°C to 140°C).
Contact Leybold Service if the sensor is defective.
Check cable connections.
Check cable. Replace the cable if it is damaged
Contact Leybold service. Principally controllers
with SR-Software Revision 302.18 or higher can
be updated for new pumps (see 3.10.2 for Conv.
SR SW-Rev).

Bearing Overload
Magnetic Bearing output current
is overloaded
Internal Overload
DC/DC Converter is overheated
Rotor Not Lifted
PK-Communication
Converter does not communicate
with the memory chip of the
pump.
The failure occurs when the fre-
quency is lower than 5 Hz.
In case of a frequency above 5
Hz a warning will occur.
Possible Cause
Pt 100 (temperature sensor bea-
ring) damaged.
Pt 100 (temperature sensor coo-
ling) is not connected.
Pt 100 damaged.
Drive / Bearing Cable is not con-
nected with the pump, pumps
